我有一个服务器，里面有电影/节目可以自动添加和转换。问题是大多数以 mkv 开头的文件在 Xbox 上都无法播放（特别是在我的网站上的 Edge 浏览器上播放）。我对转换文件不太了解，所以在尝试了我在谷歌上找到的所有组合后，我不知道该怎么做。
我该怎么做才能使它们全部正常工作？
首先，你可以想象，搜索包含关键字的任何内容Xbox并获得有用的信息非常困难。但是，我发现这篇文章似乎显示了支持的文件类型。我不知道 edge 是否有略微不同的要求：
https://www.ign.com/wikis/xbox-one/Supported_File_Types
列出的文件类型之一是mpeg 4 h264 aac我一直尝试将电影转换为但仍无法播放的文件类型。
我尝试过的一些命令：
< /dev/null ffmpeg -n -i "$i" -c:v libx264 -c:a aac -movflags +faststart -vf format=yuv420p "${name}.mp4" -hide_banner;
< /dev/null ffmpeg -i "$i" -f mp4 -vcodec libx264 -preset fast -profile:v main -c:a aac "${name}.mp4" -hide_banner;
ffmpeg -i "$i" -f mp4 -vcodec libx264 -preset fast -profile:v main -c:a aac "${name}.mp4" -hide_banner;
ffmpeg -i "$i" -f mp4 -vcodec libx264 -preset fast -profile:v main -c:v libx264 -c:a aac "${name}.mp4" -hide_banner;
ffmpeg -i "$i" -codec copy "${name}.mp4";
和更多...
希望有用的文件信息：MKV：
ffprobe -loglevel error -show_entries stream=codec_name -of default=nw=1 /var/www/html/uploads/Videos/TV/'Silicon Valley'/'Season 1'/S01E01*.mkv;
codec_name=h264
codec_name=dts
转换后的 MP4 不起作用：
ffprobe -loglevel error -show_entries stream=codec_name -of default=nw=1 /var/www/html/uploads/Videos/TV/'Silicon Valley'/'Season 1'/S01E01*.mp4; codec_name=h264
codec_name=aac
codec_name=bin_data
工作MP4：
ffprobe -loglevel error -show_entries stream=codec_name -of default=nw=1 /var/www/html/uploads/Videos/TV/'Rick and Morty'/'Season 4'/*S04E03*.mp4;
codec_name=h264
codec_name=aac
到目前为止我能看出的唯一区别是 bin-data 编解码器。但我不知道为什么它在一个上有而在另一个上没有。
非工作 mkv-mp4 上的转换日志：
# for i in /var/www/html/uploads/Videos/TV/'Silicon Valley'/'Season 1'/S01E01*.mkv;
> do name=$(echo "${i//.mkv/}");

我曾多次认为我成功地从 60 个视频中挑选出一个视频，但后来才意识到我错了。如果有其他方法可以让我获得更好的日志，请告诉我，我会的。
答案1
尝试添加这个
ffmpeg.exe -i “文件名.mkv” -target ntsc-vcd “文件名.MP4”
沒有額外的...
答案2
使用 ffmpeg 将 mkv 转换为 mp4

（关于 Windows 中的批处理 (.bat) 文件）
对于/R %%f IN (*.mkv) DO ffmpeg -i "%%f" -c copy "%%~nf.mp4"

比较用于工作文件的编解码器和配置文件。
检查输入文件流并仅映射您真正关心的流（视频/音频（以您的语言）/字幕？）

然后构建你的 ffmpeg 命令：

"S01E08.Much More.mp4"
我不确定您是否需要 -movflags 或 -faststart，它们用于在传输过程中开始播放流视频。
